CUSTOMER INTERVIEW
Interview the customer if possible, to determine the c onditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer comments. Refer to EXT-10, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that exist when the noise occurs.
 The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain
all the facts and conditions that exist w hen the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, perform a diagnosis and repair the noise that the customer is
concerned about. This can be accomplished by per forming a test drive with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so that the customer, service advis er, and technician use the same language when describing
the noise.
 Squeak – (Like tennis shoes on a clean floor) Squeak characteristics include the light contact / fast movement / brought on by road conditions / hard sur-
faces = high-pitched noise / softer surfaces = low-pitched noises / edge to surface = chirping
 Creak – (Like walking on an old wooden floor) Creak characteristics include firm contact / slow movement/twisting with a rotational movement / pitch
dependent on materials / often brought on by activity.
 Rattle – (Like shaking a baby rattle) Rattle characteristics include fast repeated contact / vibr ation or similar movement / loose parts/missing clip
or fastener / incorrect clearance.
 Knock – (Like a knock on a door) Knock characteristics include hollow sounds / someti mes repeating / often brought on by driver action.
 Tick – (Like a clock second hand) Tick characteristics include gentle contacting of light materials / loose components / can be caused by driver
action or road conditions.
 Thump – (Heavy, muffled knock noise)
Thump characteristics include softer knock / dull sounds often brought on by activity.
 Buzz – (Like a bumblebee) Buzz characteristics include high frequency rattle / firm contact.
 Often the degree of acceptable noise level varies depending upon the person. A noise that a technician may
judge as acceptable may be very irritating to a customer.
 Weather conditions, especially humidity and temperat ure, may have a great effect on noise level.
